Morphology and Distribution of Starch Granules from Trunking and Non-Trunking Sago Palm (Metroxylon sagu)

Sago palm (Metroxylon sagu) naturally grows in Malaysia and this species covers a large area in the state of Sarawak. The starch of sago palm is in its trunk. Sago palm is one of the oldest tropical plants exploited by man for its stem starch and one of the main starch-producing crops in the world....

The starch of sago palm is in its trunk. Sago palm is one of the oldest tropical plants exploited by man for its stem starch and one of the main starch-producing crops in the world.
